An unusual case of Henoch-Schnlein purpura associated with varicella zoster infection

摘要

Henoch-Schönlein purpura (HSP) is one of the most common vasculitis of childhood which is characterized by nonthrombocytopenic palpable purpura, arthritis, renal and gastrointestinal system (GIS) involvement. The etiology of HSP is mainly unknown and antecedent upper respiratory tract infection, usually viral and Streptococcal origin, drugs, cold, insect bite or some foods are the known triggering factors. HSP is rarely triggered by varicella zoster infection. In this study, we present a case with HSP following varicella infection who was admitted to the hospital because of edema and erythema in the right ankle, palpable purpura in the lower extremities and crusted lesions of varicella in his back. As a result of the case, we believe that consideration of varicella zoster as a causative agent for HSP necessitates the vaccination against it which will prevent the development of many complications of varicella zoster infection including HSP.
